| MUTATION VERIFICATION |
Sahota et al (Hum Mol Genet 3:817-818 1994) reported that DNA from this APRT-deficient subject was homozygous for a T-to-C transition at position 1759 of the adenine phosphoribosyltransferase gene. The observed change was expected to lead to a leu-to-pro substitution in codon 110 (CTG-to-CCG L110P) in exon 4. |

102600.0007; APRT DEFICIENCY |
| Identified Mutation |
LEU110PRO; In 2 sisters from Newfoundland with APRT deficiency (614723), Sahota et al. (1994) identified a homozygous mutation in the APRT gene, resulting in a leu110-to-pro (L110P) substitution. One of the sisters exhibited 2,8-dihydroxyadenine urolithiasis, whereas the other was disease-free. Sahota et al. (1994) found this patient to be homozygous for the T to C transition at nucleotide position 1759 resulting in a leucine to proline missense transition at codon position 110 [leu110pro (L110P)] in the APRT gene. |
